Araldite is an extremely strong and durable epoxy product. It's safe to use on wood, metal, glass, ceramic and even fabric surfaces. The problem is that the substance is resistant to solvents, which means you can't use a solvent to remove the adhesive. Whether the araldite glue is still wet or completely dried and cured, you can still remove it, if needed.
Saturate a paper towel with an acetone-based nail polish remover and wipe off any excess araldite glue. This method works only if the glue is still wet or hasn't completely cured yet.
Turn the item over or look at the manufacturer's recommendations to see whether it is heat-resistant. If the item is heat-resistant, set your oven to its highest setting.
Set the item on a baking tray and place in the oven. Watch through the door, looking for the glue to begin melting. If the oven has a solid door or you can't see inside, open the oven every five minutes and check.
Remove the item from the oven while wearing oven gloves once you notice the glue melting and becoming soft. Immediately scrape off the melted glue with the metal paint scraper. Remove as much of the glue as possible.
Sand down any excess araldite glue on the product, once it cools. Lightly sand against the surface of the item with sandpaper until you remove the leftover glue.
A hot-air blow gun works if the item is too big for the oven. Direct the gun at the item until the glue begins softening and starts melting. Try applying a small amount of paint stripper to the glue and waiting 20 minutes. The paint stripper should start softening the glue, which lets you scrape it off.
